functions.sh contains some functions that help you extract the sites js/html content from a HAR file & unminify it also contains a function to extract any source maps if present.
Intended Workflow:

• open devtools
• check "Preserve Log" & "Disable Cache" in network tab
• crawl the site manually
• hit the "Export HAR" button when done crawling
• than run the unhar function like this unhar www.redacted.com.har
• if there are sourcemaps also run srcmap www.redacted.com.har
• Go to the Dev Tools > Sources > Override and add the extracted folder from the HAR file
• Now refresh the page with Dev Tools open and all your dynamic analysis tools will report unminified stacktraces.
